Documentos
Comentarios(/Resúmenes)
Undertake topics related to the revised work plan to develop a feedback management (FBM) strategy for the krill fishery. This includes discussion related to the review of Conservation Measure 51-07 (stage 1 and 2) and discussion on various FBM approaches and their performances for stage 2 and beyond.
Stage 1 – continuation of the current trigger level and its spatial distribution among subareas.
Stage 2 – an increase from the trigger level to a higher interim catch limit and/or changes in the spatial distribution of catches that are adjusted based on decision rules that take account of results from the existing CEMP and other observation series
Stage 3 – a further increase to a higher interim catch limit and/or changes in the spatial distribution of catches that take account of results from an ‘enhanced’ CEMP and other observation series
Stage 4 – a fully developed feedback management strategy that is based on forecasts from ecosystem models, may involve structured fishing and/or reference areas, and includes catches up to the precautionary catch limit based on decision rules taking account of enhanced CEMP and other observation series.

As at past meetings of WG-EMM, rapporteurs will draft sections of the report. These sections will first be reviewed by the Convener and parties with strong interest in the topic and then submitted to the Secretariat for formatting, editing and circulation for reading and mark-up by attendees. Proposed changes to the draft report must be made in consultation with the rapporteurs, who will inform the Convener and then provide the appropriate changes to the Secretariat. The report will be interactively adopted in plenary, using a data projector and support from the Secretariat.
